The carboxyl molecule arrangement within the hydrocarbon ring determin

[0707]

Most of the Naphtenic crude is believed to have the chemical formula R (CH2) nCOOH where R is a cyclopentane ring and n is typically greater than 12. The naphtenic crude corrosivity is not only dependent of TAN number. Some crude of high TAN is some times less corrosive than crude with low TAN. The carboxyl molecule arrangement within the hydrocarbon ring determines the corrosivity of naphtenic crude. If the carboxyl is located inside the hydrocarbon ring, even with a high TAN, such naphtenic crude arrangement will be less corrosive than a low TAN with the carboxyl located on the extremity of the hydrocarbon ring.

1-Is the above statement correct?

2-What is the experience of the forum in the processing of Naphtenic crude?

3-To make metallurgy up grading?

4-To inject corrosion inhibitors?


Thanks in advance
